> Currently, 'hadoop fs -text myfile' looks at the first few magic bytes of a file to determine whether it is gzip compressed or a sequence file. This means 'fs -text' cannot properly decode .deflate or .bz2 files (or other codecs specified via configuration).
> It should be fairly straightforward to add support for other codecs by checking the file extension against the CompressionCodecFactory to retrieve an appropriate Codec.
